Made of 100% USA cotton, this textile is durable, comfortable, and virtually shrink-free thanks to the garment dye process. Garment-dyed means it's been washed in dye after it was sewn, so the color will stay true even after repeated washings. It also gives a broken-in feel, just like your favorite T-shirt that's been worn for a decade. The 1801 is meticulously designed with a high-ribbed collar that provides a snug, comfortable fit that will not stretch out or lose its shape over time. Cut with a spacious fit in the sleeves and torso, making it relaxed and versatile enough to wear with anything. Knitted, cut, sewn, and dyed in Los Angeles, California. This product is commonly referred to as the 1801GD or 1801Pigment.
